NITTO KOHKI Jetbroach Annular Cutter NO.16385 One-Touch Type

NITTO KOHKI Jetbroach Cutter NO.16385 One-Touch System
The NITTO KOHKI Jetbroach / Annular Cutter Model NO.16385, with a 22 mm hole diameter and a 35 mm cutting depth, is an authentic Japanese premium-grade metal and stainless steel hole-cutting tool engineered to revolutionize speed and maximize efficiency in structural steel and heavy engineering applications. Operating completely differently from traditional high-speed twist drills, the cutter utilizes an annular cutting technique that cuts metal only along the periphery of the hole, ejecting the solid center as a slug. This method drastically reduces contact surface area and friction, enabling magnetic base drills to operate at full power without overloading the motor, saving energy and cutting drilling time by up to 3 times compared to conventional drills. The resulting workpiece features high precision, clean round holes, and a smooth internal finish that is completely burr-free, allowing technicians to proceed directly with assembly without wasting time deburring, and eliminating the need for a pilot hole altogether.
